EDWIN F. GUTH, OF ST. LOUIS, MISSOURI.

LIGHTING FIXTURE.

l Application filed February 23, 1923. Serial No. 620,785.

To all whom it may concern:

Be it known that I, EDWIN F. GUTH, a citizen of the United States, residing at St. Louis, in the county of St. Louis and State of Missouri, have invented a certain new and useful Improvement in Lighting Fixtures, of which the following is a specification.

My invention relates to the art of illumination and has for its object to produce, a lighting fixture with the parts so assembled and arranged that the light rays will be delivered tothe working plane mainly by redirection from the ceiling, yet a portion of the rays will be redirected by a reflecting member.

A further object is to soconstruct this reflecting member, in its relation to the other elements of the fixture, that a part of the same is removable and interchangeable with similar parts which may be substituted.

A further object is to construct this removable part of the reflecting member, and its interchangeable companions, of different colored material so that the light rays which impinge thereon will be colored as well as redirected to the working plane, thus adding greatly to the desirability and functioning of the fixture.

My invent-ion consists of certain details of construction hereinafter set forth, pointed out in my claim and illustrated in the accompanying drawings, in which Figure 1 is a longitudinal sectional view of my device;

Figure 2 is an inverted plan view of the same.

Referring to the accompanying drawings the reference numeral 10 is used to indicate the central portion of myreflecting member which is preferably circular on its upper outer periphery, its central portion, preferably, inclining downwardly as shown. A socket 11 is placed in fixed position centrally of this reflector and registers with the orifice 12 through which a lamp 18 is projected and screwed to its seat in the socket. In the drawing the socket is shown secured to the reflector, but it may be secured in any desirable manner to provide for its proper functioning.

The outer edge surface of the reflector is flanged-01" shouldered, as shown at 14, to mate with the flangeor shoulder 15of an annular flanged ring member 16, which is secured to the central reflecting member in any desired, or usual manner.

Depending from the central reflector member, I have provided means, 17, to which a bowl, 18, is secured in proper relationship to the lamp, as shown. This means may be of any desired construction its function being to hold the plate-or bowl-in its proper fixed relationship to the lamp and reflector.

The annular flanged ring member of the reflector is preferably of a tinted composition and may be of any desired material. As stated in the objects of this invention, my purpose is to have several interchangeable annular flanged ring members of different tints, and any desired tint may be substituted at any time. This has the eifect of producing, when a change is made, a fixture which looks differentfrom the original, and this is accomplished at a minimum expense. Also the changed fixture will function differently for a different tint will be produced in the room by the different tinting of the redirected rays which impinge on the annular flanged ring.

Obviously this annular flanged ring member may be of any desired outer shape or conformation, the only requirement being that it shall have the proper inner conformation and construction to mate with the outer conformation of the central portion of the reflecting member.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is:

A lighting fixture comprising a reflecting canopy, a socket within the canopy, globe supports secured to the canopy, and a globe supported thereby, said canopy consisting of an outer annular part and a depending central part, said depending part containing a positioning flange fitting into the annular part on one end, and a flange carrying the globe supports on the other end, and being apertured for the reception of the light bulb.

EDWIN F, GUTH.
